Vishay's New 0.1-W Surface-Mount Power Metal Strip® Resistor Delivers Industry-Low 15-mΩ Resistance for Compact 0603 Package Size
MALVERN, PENNSYLVANIA — October 19, 2005 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced a new 1/10-W surface-mount Power Metal Strip® resistor that is the industry's smallest such device to combine a low 15-mΩ to 100-mΩ resistance value range, a tight tolerance of 1%, and low RTC values down to ±75 ppm/°C.
Available in the compact 0603 package size, the new Vishay Dale WSL0603 resistor serves in all types of current-sensing, voltage division, and pulse applications. It is intended for power management in cell phones and pagers; electronic automotive systems including engine controls, audio electronics, and climate controls; and disc drive motor control and dc to dc converters in computers.
With its very small footprint, low resistance values, and low RTC, the new resistor facilitates current-sensing accuracy, which in turn allows designers to use lower-cost ICs. The surface-mount WSL0603 resistor may be used in lieu of larger components or multiple high-value resistors running in parallel to provide space savings on the printed circuit board, thereby enabling design of smaller and lighter end products.
In addition to a power rating of 0.1 W, the Vishay Dale WSL0603 offers low inductance values from 0.5 nH to 5 nH, excellent frequency response, and low thermal EMF. It is rated for an operating temperature range of –65 °C to +170 °C.
The new device, which features an all-welded construction with solderable terminations, is easily placed with automated assembly equipment. It is available with a solid metal nickel-chrome alloy resistive element.
The WSL0603 is available in tape-and-reel packaging. Samples and production quantities of the new resistor are available now, with a lead time of four to five weeks for larger orders.
